Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning.
CAUTION:
As soon as the torque limiter actuates, switch off
the tool immediately. This will help prevent
premature wear of the tool.
Hole saws cannot be used with this tool. They tend
to pinch or catch easily in the hole. This will cause
the torque limiter to actuate too frequently.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.

CAUTION:
Always use the side grip to ensure operating
safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 -1 g). This chuck lubrication
assures smooth action and longer service life.
Installing or removing the bit
Clean the bit shank and apply bit grease before installing
the bit.
